Tallow for soap making is a great option for those looking to create a natural and gentle soap. It's a byproduct of rendering beef or mutton fat, and can be sourced from local butchers or meatpackers.
Tallow has a high smoke point, making it ideal for soap making. This means it can be heated to high temperatures without breaking down.
To get started with tallow for soap making, you'll need to render the fat from beef or mutton trimmings. This process involves heating the fat to separate it from any impurities.
Tallow can be used as a standalone ingredient in soap making, or blended with other oils to create a unique recipe.
Why I Use Lard—and You Should Too
I use lard in my soap because it's a waste product of the meat industry, and by using it I'm helping reduce waste and make the most of the life of an animal that was killed for steak.
Tallow and lard were the traditional fats for our homesteading ancestors because they were plentiful and cheap. It only makes sense to use them, especially if you raise and butcher your own animals.
Most tallow soap recipes include a bit of tallow with a handful of vegetable oils, but the purist in me wanted to create a 100% tallow bar, just like my homesteader ancestors would have used.
Using tallow in soap making is a great way to reduce waste, as it's often thrown out by the meat department at the end of the day. I have friends who work in the meat department who save me their fat trimmings for a day, giving me enough tallow for months worth of soap.
Tallow is an ideal fat for soap making because it provides hardness and creaminess to the finished soap bars. It's also wonderful for skin, containing an incredible amount of nutrients that are good for skin.
If you eat meat, I think you should definitely use tallow or lard in your homemade soap. If you can eat meat, there shouldn't be an ick factor – you can probably even save the tallow from your own dinners.

Getting Started
If you're new to soap making, don't worry, it's easier than you think. Rendering your own tallow takes just 2 hours.
You can start by raising your own meat, which allows you to respect the whole beast and use as much of it as possible, reducing waste.
Where to Get Tallow
You can get tallow from your local butcher shop, as it's often sold cheaply there. Rendering and using animal fat reduces wastage and creates nourishing products.
If you have animals, you can also render your own tallow from their fat. This is a sustainable way to support the environment and food production.

How to Render
Rendering animal fat is a great way to get started with making nourishing skincare products. It's a process that's not only easy but also allows you to use up animal fat that would otherwise go to waste.
You can start by collecting fat from joints, such as lamb fat, which tends to melt off easily after slow-cooking. The fat can be collected in Mason jars to save up for later use.

Rendering fat specifically for making soap is a good place to start, but you can also use fat that's been trimmed from joints and rendered for other purposes. I've found that using lamb fat is a great way to get started, as it's easy to collect and render.
It's worth noting that the type of fat you use will affect the scent of your soap, so keep that in mind if you're planning to add spices or herbs to your recipe. Rendering fat is a process that's best done at a low heat, such as in the oven or using a crockpot.
Rendering animal fat can be a sustainable way to support the environment and food production, especially if you source your fat from animals raised in a sustainable way. This can support land regeneration and the future of organic food production.
Time needed to render tallow can vary, but it's generally around 2 hours. You can also buy a bar of nourishing tallow farmstead soap if you're not interested in rendering your own tallow.
Pure Tallow Recipe
Making soap with tallow is a great way to create a nourishing and moisturizing bar. You'll need 30-32 oz of tallow or lard, depending on the recipe you choose.
To ensure accuracy, always measure ingredients by weight, not volume. This is especially important when working with lye, which can be hazardous if not handled properly.
To melt the tallow, you can use a crockpot or a pot on the stove. If you're in a hurry, a pot on the stove will do the trick, but be careful not to burn the tallow.
Once the fat is nearly all melted, it's time to add the lye. Always add the lye to the water, never the other way around, as this can cause a volcano-like reaction.
The lye and water mixture will become very hot, so be sure to handle the container with care. Stir the mixture until the lye has dissolved, then let it sit for a few minutes.

Here's a rough estimate of the ingredients you'll need for a pure tallow soap recipe:
After the lye mixture has cooled slightly, it's time to add it to the melted tallow. Use an immersion blender to mix the soap until it reaches "trace", a light pudding-like consistency. This can take anywhere from 3 to 10 minutes, depending on the speed of your blender.
Once the soap has reached trace, you can add essential oils if desired. Pour the soap into a mold, and let it set for 12-24 hours. After that, remove the soap from the mold, cut it into bars, and let it cure for 1-2 weeks.
Customizing Your Recipe
You can personalize this pure tallow soap recipe with different essential oils, creating a single scent or a blend of essential oils.
To get the best results, keep in mind that certain essential oils come through better as soap scents than others. Citrus oils are often too mild to scent soap well.
Some of my personal favorites are peppermint, lavender, and lemongrass.

Customize It

Customizing your recipe is where the magic happens. You can personalize this pure tallow soap recipe with different essential oils.
Some essential oils come through better as soap scents than others. Citrus oils are often too mild to scent soap well.
You can choose from a variety of scents, or blend different essential oils to create a unique fragrance. Some of my personal favorites are peppermint, lavender, and lemongrass.
If you prefer a more subtle scent, you can leave out the essential oils altogether, and it will be just like a traditional homesteader's tallow soap. People with very sensitive skin might find that they like the unscented version best, too.
If you're feeling adventurous, you can try blending different essential oils to create a unique scent. Here are some popular essential oil combinations:
Recipe Notes: Removed
In this recipe, tap water can cause weird results in the final soap, so it's best to use distilled water.

Distilled water is a must-have for this recipe. It removes the variable of minerals in tap water that can affect the final soap.
The recipe has a slight excess of fat, which ensures there will be no unreacted lye. This is a good thing, as unreacted lye can cause skin irritation.
This excess of fat is achieved by using a superfat of 8% in the pure tallow soap recipe. This means there is a slight excess of fat in the recipe.
You can customize the recipe by adding essential oils. However, it takes a lot of essential oil to make the soap smell strong.
Here are some essential oils that come through well as soap scents:
- Peppermint
- Lavender
- Lemongrass
Keep in mind that citrus oils are often too mild to scent soap well.
Making Tallow Soap
Making tallow soap is a unique process that requires some special considerations. Tallow soap begins resolidifying at a warmer temperature than most vegetable-based hard oils, so it's best to make soap at a higher temperature, around 125°F (52°C).
To get started, you'll need to melt the tallow. You can do this by placing it in a crockpot and heating it gently on low. I find it's easier to melt the tallow before weighing it, so you can skip this step if you've already melted it.
Tallow soap creates a naturally creamy but flat lather, which is why many recipes include additional oils like coconut and castor oil. These oils help create a fluffy lather and keep it stable.
To make a tallow soap recipe that includes coconut oil, you'll need the following ingredients:
- 20 oz tallow or lard
- 10 oz coconut oil
- 4.37 oz 100% pure lye
- 9 oz distilled water
When melting the oils together, it's essential to bring the temperature down to around 125°F (52°C). This will help prevent false trace and ensure a smooth soap-making process.
To mix the soap, start by pouring the lye water into the tallow and then use an immersion blender to mix until it reaches "trace", the light pudding consistency. This may take a few minutes, but it's worth the wait for a smooth, creamy soap.

Benefits and Considerations
Tallow creates bars that are hard, with a creamy lather that’s gentle on the skin.
Beef tallow is the most popular choice for soap making due to its accessibility, as it can be bought in blocks at many supermarkets.
Sheep tallow has a fatty acid profile that makes it a bit better at cleansing and more bubbly than beef tallow.
Unrendered fat can be a waste product and relatively inexpensive to source if you buy it from a butcher.
Benefits of Tallow Soap
Tallow soap is still made today because it creates bars that are hard, with a creamy lather that’s gentle on the skin.
Beef tallow is the most popular choice for soap making, largely due to its accessibility – you can buy it in blocks at many supermarkets.
Sheep tallow, on the other hand, has a fatty acid profile that makes it a bit better at cleansing and more bubbly than beef tallow.
Unrendered fat can be a waste product and relatively inexpensive to source if you buy it from a butcher, making it a great option for soap making.
If you raise livestock, you can render the fat from your animals and then put it to good use in soap and other recipes, reducing waste and saving money.
Environmentally Friendly Choice
Using beef fat as a soap ingredient is a responsible choice because it's a by-product of meat production that would otherwise end up in landfills.
Beef fat is a sustainable option because it's derived from animal products that are already being raised for food.
Many vegetarian soaps use palm oil, which is detrimental to the habitat of wild animals living in areas where it's grown.
Palm oil is in high demand and economical, but its production has a significant impact on the environment. Using beef fat as a soap ingredient is a way to reduce waste and make the most of animal products that are already being produced.
Tallow, a type of beef fat, is a great alternative to palm oil and other less sustainable soap ingredients.
Economical

Tallow is a cost-effective option because it's a by-product of butchering. It's often inexpensive, with some people able to get it for free by asking their butcher to set some aside.
Using tallow in your soaps can be a great way to save money. Not only is the initial purchase cost-effective, but it also hardens the soaps, making them last longer.
Raising your own beef and redeeming the fat for tallow is a great way to get it for free. This not only saves you money but also provides a sustainable way to produce soap.
